Information regarding prepaid SIM
cards
Depending on the credit and the mobile
phone provider, prepaid SIM cards may
lose their validity after a certain time.
After expiry of this period you can only
use this SIM card again if it has been
enabled by the mobile phone provider,
e.g. when more credit has been
applied.
Information on contract SIM cards
The validity of SIM cards on contract
expires upon termination at the end of
the contract.
If the mobile phone contract is to be ter-
minated, this function can be used as a
reminder of the expiry date.

Please note
An invalid SIM card will cause the
remote monitoring of the heating
system and any additional con-
nected components to cease
functioning.

idity period with "enddat", then
